摘要

本试验旨在探究饮水中添加大蒜精油蛋鸡生长性能、肠道组织形态及盲肠菌群的影响。选用200只1日龄健康状况良好且体重相近的农大三号节粮蛋鸡,随机分为4组,每组5个重复,每个重复10只鸡。各组试验鸡饲喂相同的基础饲粮,对照组正常饮水,3个试验组在饮水中添加大蒜精油,使其浓度分别为0.04、0.06和0.08 mL/L,试验期为56 d。试验期间每周记录体重和采食量,于试验第56天屠宰。结果显示:与对照组相比,饮水中添加0.04、0.06和0.08 mL/L大蒜精油极显著提高了平均日增重(P<0.01),极显著降低了料重比(P<0.01),其中添加0.06 mL/L大蒜精油的效果最明显;饮水中添加0.06 mL/L大蒜精油极显著降低了十二指肠隐窝深度(P<0.01),显著降低了回肠、空肠隐窝深度(P<0.05),极显著升高了回肠绒隐比(P<0.01),显著升高了十二指肠绒隐比(P<0.05);饮水中添加0.06 mL/L大蒜精油显著升高了盲肠中别样杆菌属、考拉杆菌属的相对丰度(P<0.05)。综上所述,饮水中添加0.06 mL/L大蒜精油有助于改善蛋鸡肠道组织形态,增加有益菌的定植,提高蛋鸡的生长性能。

Abstract

This experiment was conducted to investigate the effects of adding garlic essential oil in drinking water on growth performance, intestinal tissue morphology and cecum microbial flora of layer hens. A total of 200 one-day-old China Agricultural University No.3 layer hens with good health condition and similar body weight were randomly divided into 4 groups. Each group contained 5 replicates and every replicate had 10 chickens. Layer hens in the 4 groups were provided with the same basal diet. Chickens in the control group drunk normally and the three test groups added garlic essential oil into the drinking water to make the concentration of 0.04, 0.06 and 0.08 mL/L, respectively. The experiment period was 56 d. The body weight and feed intake were recorded every week during the experiment period. Laying hens were slaughtered at the 56th day of the experiment. The results showed as follows: compared with the control group, adding 0.04, 0.06 and 0.08 mL/L garlic essential oil into the drinking water could extremely significantly increase the average daily gain (P<0.01) and extremely significantly reduce the feed to gain ratio (P<0.01), and adding 0.06 mL/L garlic essential oil had the most obvious effect; adding 0.06 mL/L garlic essential oil into the drinking water could extremely significantly reduce the crypt depth of duodenum (P<0.01), significantly decrease the crypt depth of ileum and jejunum (P<0.05), extremely significantly increase the ratio of villus height to crypt depth of ileum (P<0.01), and significantly increase the ratio of villus height to crypt depth of duodenum (P<0.05); adding 0.06 mL/L garlic essential oil into the drinking water could significantly increase the relative abundances of Alistipes and Phascolarctobacterium in cecum (P<0.05). In summary, adding 0.06 mL/L garlic essential oil into the drinking water can improve the intestinal tissue morphology, increase the colonization of beneficial bacteria, and improve the growth performance of laying hens.
